| Abstract: | The composition and concentration of the water-soluble fraction (WSF) of four oils (Prudhoe Bay Crude, Holly Monterey Crude, Holly Rincon Crude and Isla Vista Seep Oil) are described. Changes in concentration and composition with exposure time in our bioassay chambers are described. Rapid concentration decreases and an unusual compositional relationship point to the importance of performing chemical analyses in conjunction with bioassay experiments.Comparison of the chemical composition of dissolved hydrocarbons in seawater at the Isla Vista Seep Oil site with the WSF of the seep oil shows many similarities, although the concentration is lower than the WSF by approximately 1000-fold. |
